Answer 1

2. a + b = 101.

a : b = 7 r 5

a = 7b + 5

(7b + 5) + b = 101

8b = 101 - 5

8b = 96

b = 96:8

b= 12

a= 7 x 12 + 5/

a= 101 - 12

a= 84 + 5

a= 89

3. a-b = 125

a:b = 4 r 14

a= 4b + 14

(4b + 14) - b = 125

4b - b = 125 - 14

3b = 111

b= 111:3

b= 37

a= 37 x 4 + 14/

a= 125 + 37

a= 162
